I never planned for it to happen. I was eighteen, home from college for the summer, and the house felt too quiet with Mom gone on her business trip. Dad and I had always been close, but that night the air changed. We were in the living room after dinner, beers on the table, the TV on low. He looked at me different, eyes lingering on my legs in those cutoff shorts.
"You've grown up, baby girl," he said, voice low and rough. I felt heat between my legs right away.
I shifted closer on the couch. "You noticed, huh?"
He didn't answer with words. His hand landed on my thigh, fingers pressing in. I didn't pull away. Instead I spread my legs a little, letting him feel how warm I was. He groaned, low in his chest, and slid his fingers higher until they brushed the edge of my panties.
"Fuck, you're wet already," he muttered. He hooked a finger under the fabric and yanked them aside, rubbing my clit in slow circles. I gasped and pushed into his hand. "Daddy's little girl is dripping for this."
I reached over and grabbed his cock through his jeans. It was thick and hard, straining the denim. I unzipped him and pulled it out, wrapping my fingers around the shaft. He was bigger than I remembered from accidental glimpses growing up. Veiny, heavy, the head already leaking.
"Suck it," he ordered. I dropped to my knees between his legs and took him in my mouth. No teasing, just straight to it. I bobbed my head, taking him deep until he hit the back of my throat. He grabbed my hair and fucked my face, hips thrusting up. Spit ran down my chin onto my tits.
"Goddamn, that's good," he growled. "Been thinking about this for years."
He pulled me up, spun me around, and bent me over the arm of the couch. My shorts and panties hit the floor. He kicked my feet apart and lined up behind me. One hard thrust and he was inside, stretching my pussy wide. I cried out, half pain, half pleasure. He didn't stop. He pounded me, balls slapping against my clit with every stroke.
"Take Daddy's cock," he grunted. "This tight little cunt was made for me."
I pushed back, meeting every thrust. The wet sounds filled the room. He reached around and rubbed my clit fast and rough until I came, shaking and clenching around him. He kept going, fucking me through it, then pulled out and flipped me onto my back on the floor.
He shoved back in, missionary now, my legs over his shoulders. His eyes locked on mine while he railed me. "You like being Daddy's fucktoy?"
"Yes," I moaned. "Harder."
He gave it to me. Sweat dripped from him onto my chest. He pinched my nipples, twisted them, then leaned down and sucked one into his mouth, biting just enough to sting. My second orgasm hit faster, my walls pulsing around his cock.
He pulled out again, flipped me onto all fours, and spread my ass. His tongue dragged over my asshole, then he spit on it and pushed two fingers in while his cock stayed buried in my pussy. The double stretch made me whimper.
"Gonna fill both holes one day," he promised. For now he focused on my cunt, slamming in deep until his rhythm broke.

He buried himself to the hilt and came, hot pulses flooding me. I felt every spurt.
We didn't stop there. He stayed hard enough to keep going after a minute, rolling me onto my side and spooning me, one leg hooked over his. Slower strokes this time, his hand around my throat, whispering how long he'd wanted to breed his own daughter. I came again when he told me to.
Later, in his bed, he had me ride him. I bounced on his cock while he held my hips and thrust up. Cum leaked out of me down his shaft. He made me lick it off, then fucked my mouth again until he shot down my throat.
We passed out tangled together. Morning came and we didn't talk about stopping. He fucked me in the shower, bent over the sink, cum running down my thighs. By the time Mom's trip ended we had a new routine: quiet, filthy, and ours.
Every night after that I waited for him to come to my room or drag me to his. Raw, no condoms, just skin on skin and the filthy words that made us both lose control. It was wrong. It was perfect. And it never felt like enough.
